FASTENER Filed July 19, '1947 INENTOR. Geowg F. Dixon ATTORNEYS Aparticularly useful feature of the present fastener is the facility withwhich it may be attached without rope or straps to an upright post of aninfants crib. Such a post is indicated at 4 and may be closed orinaccessible at both ends as by the top and bottom rails of the crib.Thus it becomes necessary to assemble the fastener on the post withoutpassing the fastener over the end of the post. To place the frame Iabout the post 4 the slide clamp 2 is first disassembled or removed fromthe frame t' so that elongated cen-- tral opening l5 of the frame isclear. The frame l which is normally substantially fiat with its severalparts disposed in a common plane is then sprung or twisted to the shapeshown in Fig. 3'; in which the sides 8 and 9 are distorted from. theirnormal positions indicated by the broken lines to the curved positionsindicated by the solid lines.

The sides 8 and 9, when so distorted, are disposed in divergent curvedplanes and the ends thereof carrying the lateral extensions Il and i2are sufficiently far -apart to pass the' post li into the centralaperture l5 of the clamp frame. After passing the post l past thellateral extensions ll and l2 ofthe frame the latter, byl reason of itsinherent resiliency, snaps itself or moves back to its normal flatposition. Thereafter the slide or clamp 2 is assembled on the frame I inthe manner previously described andthe fastener is ready for use.

To secure in the fastener apiece of fabric m-aterial such as the blanket3 an end corner I6 of the blanket is first passed upwardly through thecentral opening l5 of the fastener behind the cross bar or clamp 2. Theblanket corner is then drawn forwardly over the top of the cross bar 2and passed downwardly between the cross. bar and the lateral extensionsI'I and I2` of the frame, The portion of the blanket that is engagedbetween the bar 2 and the lateral extensions l l and i2 of the frame istightly clamped in place, any force orv tug on the blanket' proper tendsto draw the cross memberv 2 tightly against the lateral extensions Iland l2` more securely to pinch and retain the blanket portion there'-between.

As shown in Fig. 2 the plane of thel crossl bar or clasp 2 is at a rightangle or substantial-ly normal to the plane of theA rectilinear frame I.parts of the fastener maintain themselves in this right angled orperpendicular relationship` by reason of the relatively close flt of thesides 8 and 9 in the elongated openings 6 of the slides As shown in Fig.5 onlysliding clearance is provided between the frame and the sides ofthe openings or apertures 6 so. that'y twisting of the cross bar orclamp Y2 is minimized'.

Although the clearance between the slide bar or clamp and the sidemembers of the frame is suiiiciently close to restrict the twisting ofthe clamp bar on the frame the clearances in the ends of the elongatedaperturesb are sufficient. to pass the extensions Il and l2 bodilythere.- through when the sides 8 and 9 are sprung apart permitting theextensions to clear the cross, meinber or bridge of the clamping bar.

The-principles of the present invention may be utilized in various ways,numerous modifications and alterations being contemplated, substitutionof parts and changesv in construction being resorted to as desired, itbeing understood that the embodiment shown in the. drawings. anddescribed above is given merely` for purposes of. explanation andillustration: without intending,

What I claim is:

1. In a fastener of the frame and sliding clamp bar type in which theframe has spaced side members and cross members and the sliding barassembled on the frame is apertured to receive the side members of theframe and is movable toward and away from one of the cross members of:the frame to clamp material' to:y be fastened therebetween, theimprovement which comprises the combination of a cross element on thesliding clamp bar and a transverse slit severing said one cross memberof the frame, the slit being so disposed as to pass the cross element ofthe clamp bar therethrough upon distortion of the frame, the undistortedframe normally holding the slit closed to retain the clamp bar assembledon the frame;

2. A fastener comprising a generally U-shaped frameV member havingspaced leg portions and lateral extensions on the leg portions directedto.- vvard one another, theV lateral extensions` being I aligned andhaving confronting ends substantially in abutment, and a slide clamphaving, spaced openings separated by a cross element.. the slide beingreceivable on the frame member upon. springing apart of the leg portionsof the latter to pass the cross element between the confronting ends ofthe lateral extensions, the no1=- mal space between said confrontingends bein-gI less than the width of the cross element whereby engagementof the cross element and one or both-` of the lateral extensions retainsthe slide in assembled relationY on the U-shaped member.

3. A fastener comprising a resilient U-shaped frame member having spacedleg portions and lateral extensions on the ends of each leg portion,the. lateral extensions being directed toward, one another tosubstantially abut one another and normally substantially closing theend of the frame, and a slide clamp substantially of figurey 8 shapereceivable on the U-shaped frame member, said slide clampv havingelongated openings f for receiving the leg portions of the frame memimembers each having a lateral extension at the split end, and a clampslidably mounted onsaid frame side members, the frame being deformabletospread the side membersl and lateral extensions for removal of the clampfrom and assembly of 'the cla-mp on the frame, said' clamp having twoyelongated apertures substantially in. end to end relation and a bridgeintermediate said apertures, said elongated apertures of the clamp beingshaped to pass the spread lateral extensions and frame side members, andsaid bridge being disposed to pass through the end split during suchremoval' and assembly.

5. A holding device comprising a resilient frame including spaced sidemembers having lateral extensions directed toward one another andl aclamp slidable on the side members; the cla-mp having a pair of spacedapertures to receiver the side members and a stop element between. theapertures, said` stop element being disposed normally to engage at leastone. of the. lateral einl tensions to retain the slide clamp assembledon the frame, the apertures being suii'iciently large to simultaneouslypass the lateral extensions therethrough upon distorting the frame tomove the lateral extensions relative to one another to permit passage ofthe element between the eX- tensions for disassembly and reassembly ofthe slide clamp and the frame, the frame in use be ing retained innormal shape by its inherent resiliency and being returned to normal byinherent resiliency upon release after said distortion.

6. A holding device comprising a resilient frame member having spacedside portions and inturned ends on the side portions directed toward oneanother and separated by a slit, and a, clamp member apertured toreceive the side portions of the frame member and slidable along thelatter when assembled with the frame member, the inturned ends of theframe member being disposed normally to engage the clamp member toretain it assembled on the frame member, the apertures in the clampmember being large enough to pass the inturned ends of the frame memberand having a different spacing from that of the slit between theinturned ends to require slight deformation of the frame to pass theinturned ends through the apertures in assembly and disassembly of themembers, the frame member being adapted, upon release, to return tonormal by inherent resiliency.

7. A holding device comprising a resilient frame member having spacedside portions and inturned ends on the side portions directed toward oneanother, the side portions and ends of the frame member all beingnormally disposed in a common plane, and a clamp member apertured toreceive the side portions of the frame member and slidable along thelatter when assembled with the frame member, the inturned ends of theframe member being disposed normally to engage the clamp member toretain it assembled on the frame member, the apertures in the clampmember being large enough to pass the inturned ends of the frame memberand being slightly displaced from the normal positions of the inturnedends to require slight deformation of the frame to pass the inturnedends through the apertures in assembly and disassembly of the members,the frame member being adapted, upon release, to return to normal byinherent resiliency.

8. A holding device comprising a frame member of resilient plasticcomposition having spaced integral side portions and integral inturnedends on the side portions directed toward one another, and a clampmember also of plastic composition apertured to receive the sideportions of the frame member and slidable along the latter whenassembled with the frame member, the inturned ends of the frame memberbeing disposed normally to engage the clamp member to retain itassembled on the frame member, the apertures in the clamp member beinglarge enough to pass the inturned ends of the frame member and beingslightly displaced from the normal positions of the inturned ends torequire slight deformation of the frame to pass the inturned endsthrough the apertures in assembly and disassembly of the members, theframe member being adapted, upon release, to return to normal byinherent resiliency 9. A fastener comprising a resilient frame havingspaced side members formed at one end of the frame with lateralextensions directed toward one another, a clamp member formed withspaced apertures to receive the side members or the frame, said clampmember apertures being substantially of the same general shape as andlarge enough simultaneously to pass the lateral extensions of the sidemembers and being at a diierent spacing from the normal spacing of thelateral extensions of the frame to require slight deformation of theframe from normal to pass the lateral extensions thereof through saidapertures in assembly, the frame returning to normal by inherentresiliency from said slight deformation whereby the different spacing ofthe apertures with respect to the normal lateral extensions retans theclamp member assembled on the frame.
